Construction details of the model will not only be shown as jpeg files, but also as special files that can be viewed with VirtualMEC, a dedicated 3D CAD application for Meccano model building.
VirtualMEC is available as a stand-alone Windows application and a demo version can be dowloaded from www.virtualmec.com

Using the demo version will enable you to view a 3D drawing of the model from any angle you wish.
Click here to download a mdl file of the complete model; 175 kB.
Regular users of VirtualMEC may have to download the latest version because this drawing uses some parts that were not available in previous releases.

Note that I have cheated just a little when creating these drawings. The parts list does not yet include a modern canister type electric motor so I have 'made' one out of a pile of wheel disks and a few odds and ends! Also note that difficult things like driving bands and sprocket chain are yet to come and I have deliberately changed some colours for clarity.

 
 
     
     
 

About the Model:

This one is loosely based on Chris Shute's Percy - The Ping-Pong Porter. I say loosely because I have corrupted Chris's concept for my own ends. Chris produced a model plan for his version and this was published in the September 2002 edition of Constructor Quarterly so if you have a copy of this CQ it might be useful to refer to that as well.

I just love this animated doll which is Percy. I think of him as very human. In fact, as I said to Chris at Skeggy, if he was any more human I would be challenging Chris for custody! The above picture is a general view of the model and for the benefit of those spanners who have never seen Percy in action, what happens is that Percy crouches down at one side of the ball tracks and receives into his arms one of the Ping-Pong balls. He then straightens while sliding over to the other end of the tracks. When he arrives there, he opens his elbows a bit and drops the ball back on to the track. This ball then runs around the track and back to the beginning. Meanwhile Percy slides back and crouches down again ready to receive the next ball.

This process continues ad-infinitum.
